Structured Cabling
Comprises of cables and associated hardware parts Provides an organized way of low voltage wiring
Transmits data that is built in structured form
Need of structured cabling: Consistency
Standard cabling systems for Data, voice
and video
Cost Reduction Reduces the cost by reducing thenumber of cables
TroubleshootingIsolates and fixes the problem
Mobility Network resources are portable

Cable DistanceI
Horizontal Cabling Distance
horizontal cabling distance is 99 meters (TIA/EIA-
568A)
6 meters of patch cable 90 meters horizontal (routed in the wall)
3 meters of station cable
99 meters total (rounded off to 100 meters)
Backbone cable Distance
Depends on type of cable beingused and on its
location

Pulling Cables - I
While dealing with structured cabling you have topull out the cables from some conduits and punch
down the free end of the cable
Conduits are PVC or flexible plastic pipes used to
organize the cables Pull twine through the conduits

Working with CablesI
Installation works in three stages:
Running cable from central point to the room
Wall jacks are mounted and cables ended into jacks
Wire cables from the central end to switchboard Color Coding
Helps to classify different types of wires
Patch cable and cross over cable can be differentiated
on the basis of colour coding

Working with CablesIV
Weak Link Mostly, weakest link is the station cable, which runs
from wall to desktop
Information Outlet
Protect horizontal wiring from physical handling thatcables receive
Keep installation neat and eliminate unsightly snakepit of unused cables coiled on floor
Station Cable
Runs between information outlet
and network node e.g. PC

Cross-Connect Devices - I
Make easy to reconfigure horizontal and backbonewiring
Terminates cable or group of cables
Make terminations available for interconnection to
other cables
In data networks Small cross-connect device will
terminate backbone cable and make it available for
connection to wiring hub
In wiring hub Larger cross-connect device will
terminate horizontal wiring before it enters hub

Case Study 1
The network administrator of the Mumbai branch of
MoneyMaker bank is facing difficulties in
maintaining the network. In case the network goesdown due to some hardware failure, identifying the
source of the problem and troubleshooting it is very
time consuming. The layout of the network has not
been changed since the time it was set up.

Chapter 7 39
Solution
Deploy a dedicated closet
Use full equipment cabinet
Use rack and configure the hardware
Use appropriate cable and crimp the cable
Define maximum backbone cable length andhorizontal cable length
Use different wire manager
Use modular outlet and I/O plate
Use third party hardware monitoring or the
troubleshooting devices

Summary - I
Structured cabling system is a set of cabling whichinterconnects different equipments in anorganization in a structured manner
Cable connectors are used to connect the cables
Cabling tolls are helpful to make connectionbetween the cable and the connector
Colour Code helps to identify the types of wires
Cat5 cables are punched into Information outlet (IO)
as per the colour coding
Jack Panel is used to connect horizontal cabling tonetwork

Summary - II
Straight through cables have the pin outconnections similar at both the ends
Cross over cable change the pin out connections atone end
Installing the rack explains how to place networkingequipments and accumulate different smallequipment on the tray of the rack
Wire manager can organize the disorganized cables
and makes it easy to access Labeling the cables help you to identify the path of
the cables and makes the troubleshooting easy
